With great power, comes great battery responsibility, said one of our scribbling colleagues. When that high-end smartphone of ours shows great skills into rendering powerful applications without missing a detail but the packed battery lacks enough juice to keep it alive until the end of the day, you need a battery management solution.

While the Android market is filled with great power monitors such as Battery Status Plus and there are a couple of good practices that can also help, from the plains of the XDA forum comes Quad Core Manager, a rather simple software which allows users to disable processing cores, one by one. Aimed solely at rooted phones with quad-core processors, this application can spare some vital battery juice in case you desperately need it.

Quad Core Manager: how it works

Before giving it a shot, you must know that Quad Core Manager only works for rooted Android terminals and it has been found incompatible with some LG and Samsung models, mainly because it’s a software still in testing. Actually, the current package is in a trial that ends on July 30th, a date after which a new, more enhanced trial will be activated.

When it comes to features, this is what Quad Core Manager packs under the hood:

Manual core control – using two simple buttons, one for disable and one for enable, users can manually deactivate non-primary cores and save battery, when they are not needed.

Persistent mode – when enabled, the persistent mode will deny any other application or even the Android platform to re-enable your cores, bestowing users full rights over their phone.

Start on boot – as the name suggests, this option which is disabled by default can remember settings even after restarting the device and apply them automatically.

ACOO – Automatic Cores ON/OFF is a small automation features, which turns OFF cores when the screen is dimmed and activates them back when the phone is not idle. Also, it supports a small customization feature, from which owners can define two advanced and alternative ways of turning ON/OFF cores that depend on custom events (let’s say entering a demanding game). Unfortunately, ACOO is enabled only for 15 days, afterwards a small donation will be required to continue using it.

Seaskyways, the developer of the package, has announced that even more functionality, as well as extended compatibility, will be added in the near future. If you want to test the application, it can be found on Google Play.
